edgetek™ pke polyketone formulations replace nylon, reduce carbon footprint the edgetek pke series consists of specialty engineered polyketone (pk) thermoplastics. available with common fillers or impact modifiers to enhance performance, these formulations provide excellent chemical resistance, low moisture uptake, excellent dimensional stability, and high impact and wear resistance. these properties offer manufacturers a high-performing, cost-competitive and more eco-conscious alternative to nylons (pa66 and pa6).
what is polyketone? aliphatic polyketone, often referred to as just polyketone or pk, is a semi-crystalline engineering resin that is an alternating copolymer of carbon monoxide and ethylene with some propylene (1–10%). it has good tensile, thermal, flex, and impact properties like nylon (pa), while maintaining the excellent wear, chemical resistance, and dimensional stability of acetal (pom).

this review aims to report the status of the research on polyaryletherketone-based thermoplastic blends (paek). paek are high-performance copolymers able to replace metals in many applications including those related to the environmental and energy transition. paek lead to the extension of high-performance multifunctional materials to target embedded electronics, robotics, aerospace, medical devices and prostheses. blending paek with other thermostable thermoplastic polymers is a viable option to obtain materials with new affordable properties. first, this study investigates the miscibility of each couple. due to different types of interactions, paek-based thermoplastic blends go from fully miscible (with some polyetherimides) to immiscible (with polytetrafluoroethylene). depending on the ether-to-ketone ratio of paek as well as the nature of the second component, a large range of crystalline structures and blend morphologies are reported. the paek-based thermoplastic blends are elaborated by melt-mixing or solution blending. then, the effect of the composition and blending preparation on the mechanical properties are investigated. paek-based thermoplastic blends give rise to the possibility of tuning their properties to design novel materials. however, we demonstrate hereby that significant research effort is needed to overcome the lack of knowledge on the structure/morphology/property relationships for those types of high-performance thermoplastic blends.
polyetheretherketone peek there are many applications that require high-pressure seals, such as down-hole safety valves, water jet intensifiers, and oil and gas valves. peek, short for polyetheretherketone, is a high performance engineering polymer thats a common choice for high pressure seals. lets see why want to stay ahead of the curve? check […]
polyetheretherketone (peek) is the leading high-performance thermoplastic biomaterial that can be processed through material extrusion (me) additive manufacturing (am), also known as three-dimensional (3d) printing, for patient-specific load-bearing implant manufacture. considering the importance of cyclic loading for load-bearing implant design, this work addresses the high-cycle fatigue behaviour of 3d-printed peek. in this work, printed peek specimens are cyclically loaded under stress-controlled tension–tension using different stress levels between 75% and 95% of printed peek’s tensile strength. the experimental results are used to document 3d-printed peek’s fatigue behaviour using basquin’s power law, which was compared with previous fatigue research on bulk peek and other 3d-printing materials. as a pioneering study on its fatigue behaviour, the results from this work show that 3d-printed peek exhibits an above-average fatigue strength of 65 mpa, corresponding to about 75% of its tensile strength. fracture surface analysis suggests that a transition can occur from ductile to brittle fracture with maximum stresses between 85% and 95% of the tensile strength. evidence of crack propagation features on fracture surfaces under scanning electron microscope (sem) observation suggests crack initiation in void defects created by printing deposition that propagates longitudinally through line bonding interfaces along layers. considering this, 3d-printed peek’s fatigue behaviour can be strongly related to printing conditions. further research on the fatigue behaviour of 3d-printed peek is necessary to support its use in load-bearing implant applications.
